Question

6g of hydrogen at 1.5 atm and 273c occupies a volume of

Answer 1

Answer:

volume =89.544L

Explanation:

Assuming hydrogen is an ideal gas :

The ideal gas eq.=PV=nRT

where P is pressure, V is volume , n is no. of moles, R is gas constant , T is temperature.

Molecular mass of hydrogen gas =2g/mol

no. of moles = mass/molecular mass

=> n= 6/2= 3

also,

Temperature in Kelvin= temperature of Celsius+273

=>T= 273+273= 546K

put the value in ideal gas eq :

PV=nRT

1.5×V= 3×0.082×546. (R=0.082 atmL/mol/K)

V = 89.544L
